It's almost working, but the clocks drift apart.

My setup is a Roland MV-8800 connected to the VS-2480 over R-Bus. (Digital audio passes just fine.)

I set up two empty projects at 100bpm, with the MV as Master and VS as Slave (all as described in the manuals). And after 4 minutes of playback, I've got:

MV: 4:12.27 and 106-02-259
VS: 4:13.01.03 and 106-02-347

I did the same test over a MIDI connection and got the same result. Have tried with MIDI clock and MTC, and with Master/Slave roles reversed.

The only way I can get them so stay close is if I make the MV-8800 tempo 100.05bpm, when - after 4 minutes - they are now just 1 tick apart.

I'm guessing that there's something I'm not quite setting correctly, but after trying just about every combination of MMC/MTC/ext/int clock, I'm struggling.

Any ideas?

(I've also asked this at the reborn MV Nation.)

I've never used the MV but have you tried syncing both MV and the VS to a dedicated external clock?

Don't think the MV has word clock input (at least not the usual BNC connector).

I'm an MTC/midiclock newbie so not completely sure how tight I should expect the syncing to be.

The MV8000 defults to 100bpm and the VS2480 to 120bpm could that be the drift?

No, I did spot that quite quickly, and set the VS to 100bpm. I tried altering the VS bpm but it only has 0.1bpm increments. The MV is finer - 0.01bpm, and as I posted, if I set the MV to 100.05bpm it's a lot closer after 4 minutes.

If I use the Master (MV) transport controls, or alter the bar-beat-tick setting by hand, the Slave (VS) immediately jumps into perfect alignment. That sort of implies to me that there is NO ongoing sync, and that it's just the MMC Play/etc commands that are being received.

For sure, there's no other visual sign that the two machines are in sync.

As I say, I'm a syncing newbie, so I'm scrabbling a bit.

(I'm about to go on holiday but will check back for advice - I appreciate your help, guys)

Perhaps digital sync via R-bus is the other way 'round than midi sync?
